Hello Edwin,
D120LSW does not exist as a model name, and most likely refers older D120-LS models, like non-JCT ISA boards. Let.s forget about that, it is long time retired product
D120JCT series are Universal PCI or PCIe form-factor boards, and they are supported under SR 6.0, however, some models of this series are retired as well. Please take a look at http://www.dialogic.com/en/products/others/retired-products.aspx for complete list of such products.
PCI-U and PCIe-based D120JCTLS boards have the same feature set, found at http://www.dialogic.com/en/products/media/jct/d120jct.aspx,
